[Canon] IV | Film Cameras | April 1951
The camera featured a three-mode optical viewfinder and showcased Canon's innovative technology, including cordless flashbulb synchronization through built-in contacts on the flash unit rail, eliminating the need for cumbersome synch cords. This design allowed for automatic switching between FP-, F-, and M-sync contacts when attaching the dedicated Flash Unit X. Starting in the latter half of 1951, the original collapsible Serenar 50mm f/1.8 lens was replaced with a fixed-barrel lens.
